The wear-resistant coating applied on an icebreaker needs to have the properties of cold resistance, wear resistance and corrosion resistance. The wear-resistant coating needs to be tested for wear resistance after production. The following problems exist in the test process. 1. When the performance of the wear-resistant coating is tested, the sliding friction resistance and the rolling friction resistance of the coating need to be tested at the same time. The existing test equipment can only test the wear resistance in one state, and the test result deviates from the actual performance of the coating, thereby reducing the accuracy of the test.

[0032] Please refer to Figure 6 、 Figure 8 、 Figure 9 and Figure 10 , the force storage and excitation assembly 65 comprises two fixed legs 653 fixedly connected to the front side of the mounting groove 7 in a symmetry, a second mounting plate 652 fixedly connected to the top of the two fixed legs 653 in common, arc-shaped toothed racks 651 fixedly connected to the left and right ends of the second mounting plate 652 and engaged with the third gear wheel 639, the centers of the two arc-shaped toothed racks 651 coinciding with the axis of the fixed shaft 68, so that the third gear wheel 639 and the arc-shaped toothed racks 651 can be in engagement during reciprocating swing.

[0033] In use, first, part of the arc-shaped substrate 642, part of the second flat substrate 644 and the plate with wear-resistant coating on the part of the impact plate 637 are placed in the freezer for freezing. The coating on the above-mentioned plate is changed in performance after a long time of freezing and testing immediately after freezing. Although the test process will slowly warm up, it has little effect on the test results. The frozen second flat substrate 644 is installed in the base 643 by screws. The frozen arc-shaped substrate 642 is inserted into the arc-shaped shell 641 and is fixed by glue. The frozen plate with wear-resistant coating is screwed onto the impact plate 637. At the same time, the coating on part of the unfrozen plate is compared with the above-mentioned frozen plate. Before testing, the test ball is placed in the cavity surrounded by the impact plate 637, the arc-shaped substrate 642 and the base 643. Then the arc-shaped shell 641 is screwed onto the base 643. The second servo motor 612 is started. The output end of the second servo motor 612 drives the rotating disc 613 and the limiting pin 617 thereon to rotate. The limiting pin 617 drives the swing tooth block 614 to rotate around the fixed pin 616. Through the meshing of the fixed pin 616 and the second gear 618, the fixed shaft 68 and the support seat 66 thereon are synchronously driven to reciprocate, thereby driving the first mounting plate 62 and the base 643 thereon to reciprocate, indirectly driving the ball to reciprocate. While swinging, the ball rolls and rubs the coating on the arc-shaped substrate 642 and the second flat substrate 644, simulating the performance of the coating under rolling friction. During the swinging process, the third gear 639 and the arc-shaped rack 651 mesh, and the third gear 639 and the linkage shaft 633 thereon are driven to rotate, synchronously driving the half gear 632 to rotate. When the half gear 632 is meshed with the second straight rack 631, the second straight rack 631 and the extension rod 635 thereon are driven to move away from the second flat substrate 644, and the impact plate 637 is driven to move away from the second flat substrate 644, compressing the force storage spring 638. When the swing reaches the maximum one-sided angle, the ball rolls and accumulates on one side of the impact plate 637 under the action of gravity. During the rolling process, the rolling friction is simulated to facilitate the testing of the performance of the coating under rolling friction. At this time, the half gear 632 is disengaged from the engagement with the second straight rack 631, and under the restoring force of the force storage spring 638, the impact plate 637 is quickly knocked out to quickly knock the grinding ball from one side to the other side. The grinding ball impacts the plate material with a coating on the other impact plate 637, and at the same time, it may impact the coating on the second plane base plate 644 and the arc-shaped base plate 642, which is beneficial to simulate the performance of the coating under the impact state. When rotating in the opposite direction, the half gear 632 rotates in the opposite direction. At this time, the telescopic rod 635 is compressed and shrunk. The telescopic rod 635 is a two-section telescopic sleeve. During the compression process, the compression restoring spring is compressed. When the half gear 632 is disengaged from the engagement with the second straight rack 631, the second straight rack 631 is restored to the initial position under the elastic force of the restoring spring at this time. The initial state is the longest extension state of the telescopic rod 635. At this time, the force storage spring 638 on the other side is charged, so that the force storage and knocking are realized during the reciprocating swing.

[0034] It should be noted that when using the wear-resistant coating wear testing device, before testing, record the initial state of the plate material with a wear-resistant coating on the first plane base plate 532, the arc-shaped base plate 642, the second plane base plate 644 and the impact plate 637, including weight, surface state, for comparison with the state after testing. According to the testing requirements, the wear-resistant coating to be tested is coated on the plate material with a wear-resistant coating on the first plane base plate 532, the arc-shaped base plate 642, the second plane base plate 644 and the impact plate 637, and is placed in a cold storage to realize freezing of the coating. Subsequently, the clamping assembly 53 is used to clamp and fix the first plane base plate 532. The clamping assembly 53 clamps the frozen and unfrozen first plane base plate 532 at the same time, and the two are compared. After clamping is completed, the cooperation between the driving assembly 51 and the reciprocating rotation assembly 52 is used to realize the reciprocating rotation of the first grinding head 527. The reciprocating rotation testing of the coating is realized by using the first grinding head 527. The cooperation between the driving assembly 51 and the reciprocating linear motion assembly 54 realizes the reciprocating linear friction of the coating, which is convenient for simultaneously performing the reciprocating rotation friction test and the reciprocating linear sliding friction test of the coating. During testing, there is no need to replace the equipment.
